NCSC Director Wes Street

The National Counterintelligence and Security Center (NCSC) is a component of the Office of the Director of National Intelligence and serves as the U.S. government’s primary organization for integrating and coordinating counterintelligence and security activities. Its mission is to help identify, detect, deter, disrupt, and mitigate foreign intelligence threats while strengthening national security across the executive branch.

NCSC develops strategic plans, policies, standards, and guidance to protect classified information, sensitive facilities, personnel, information systems, and other national security assets. Its work includes producing strategic threat assessments, coordinating counterintelligence collection and targeting, and advancing personnel vetting, security clearance modernization, and insider risk management. The Center also promotes consistent security practices and supports efforts to build a trusted national security workforce.

NCSC engages with federal agencies, academia, and the private sector to raise threat awareness and reduce security risks. It provides resources on counterintelligence, secure innovation, threat awareness, and supply chain risk management, as well as training in insider threats, operational security, personnel security, sensitive compartmented information security, and SCIF management.
